How do you find mass of a solute when cubic centimeters and molarity is given?
You know the molarity and you know the volume. First off you find the moles. Molarity divided by 1000, multiplied by the volume in cm^3. Then you multiply the moles by the molecular mass of the solute, to get the weight in grams.
Could you calculate the molarity of a solution you need to know the moles of solute and the?
volume of the solution
Why doesn't adding one mole of solute to one liter of water make a one molarity solution?
molarity of moles of solute/liters of solution(not solvent) the volume of the solvent(even if it started at 1 L) would change after adding the solute depending on the molar mass, density, etc of the solute, the molarity would be different
What is the molarity a measure of?
Molarity (M) indicates the number of moles of solute per liter of solution (moles/Liter) and is one of the most common units used to measure the concentration of a solution. Molarity can be used to calculate the volume of solvent or the amount of solute.
What information is necessary to determine the molarity of a solution if the chemical formula of the solute is known?
You know the chemical formula. You can get the molecular weight from this. You need the end volume and you also need the mass of solute.
How do you calculated the value for molarity?
Molarity= No. of moles of solute/Volume of solution(in litre) or No. of moles of solute*1000/Volume of solution(in ml)
Why molarity not based on the volume of solvent alone?
Because molarity depends on the concentration of the solute.
Definition of molarity and its equation?
molarity is the number of moles dissolved per volume of a solution in dm cube molarity=mass of solute in gram __________________ 1 * _________________ molecular mass of solute volume of solution in dm cube OR molarity=no.of moles ________________ volume of solution in dm cube
How do you calculate molarity of substance?
Molarity (M) = mole of solute (mol)/volume of solution that it is dissolved into (L) Make sure that the volume is converted to L if it isn't already, otherwise you will get wrong answers.
Why did chemists develop the concept of molarity?
It helps to quantify the concentration of solute in any solution - molarity is calculated by dividing the amount of solute by the total volume of the solution. The unit of molarity is moles/L.

To calculate the molarity of a solution, you need to know the moles of solute and the?
You need to know the moles of solute and the VOLUME of SOLUTION.

How many equivalents are there in 15 ml of concentrated Hcl which is approximately 12 molar in concentration?
molarity = number of moles of solute / volume of solution number of moles of solute = molarity x volume of solution number of moles of solute = 12 (mole/L) x 15/1000 (L) number of moles of solute = 0.18 mole
What is the molarity of a solution containing 7.0 moles of a solute in ml of solution?
The molarity of a solution containing 7.0 moles of solute in 569mL of solution is a)81M b)0.081M c)12M D)4.0M The answer is C. 12M 7 x 1000/569 = 12.302
